In which condition will carbon dioxide have higher solubility in water?
Answer and explanation
Correct answer: High pressure and low temperature
Carbon dioxide is a gas, so increasing its partial pressure above water generally increases the amount that dissolves. Lower temperature also favours retention of dissolved gas because gas molecules have less tendency to escape. Thus high pressure combined with low temperature gives higher CO₂ solubility than the listed alternatives. High temperature does not make solubility automatically zero, and low pressure is less favourable.
